HTMLB and JavaScript

Hi,

I am using HTMLB in my JSP page.Is there any way to hide or show the HTMLB components when the page is loaded, like HTML onLoad() calling javascript.

expecting some sample code from HTMLB experts.really i stuck wih this problem for 2 days.

For example.....i have one DropdownList box.Based on the selected dropdown values ,i need to show and hide one InputField and another Dropdown.

Regds,
